US Patent:

56993099, Dec 16, 1997

Filed:

May 13, 1996

Appl. No.:

8/645377

Inventors:

Daniel R. Cronin - Lake Worth FL
Ricardo Fernandez - Miami Beach FL

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

G11C 700

US Classification:

365203

Abstract:

A data processing system (10) for providing memory access to a memory (18). The memory (18) includes a memory array (43) having a plurality of memory cells arranged in rows and columns and an address decoder (42) for accessing a memory cell (44) of the memory array (43) in response to decoding an address signal. Precharge logic (49) coupled to the memory array (43) and the address decoder (42) enables, in a high performance mode, all columns of the memory array (43) prior to accessing the memory cell (44). In a low power mode, the precharge logic (49) enables only selected columns of the memory array (43) prior to accessing the memory cell (44).

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

G06G 748
H01L 23528

US Classification:

39550002

Abstract:

In operation, a standard cell library having diode place-holders (16) associated with standard cell inputs (12) is used to design a standard cell-based semiconductor device. Each standard cell in the standard cell-based semiconductor device is analyzed to determine if its standard cell inputs (12) will be connected to a conductive element (18) during processing that can accumulate a charge. When a conductive element (18) that can accumulate charge is identified, the diode place-holder (16) associated with its standard cell input (12) is replaced with a diode (16).
